This invention relates to an apparatus for flushing drains and which may also be employed for various cleaning purposes.

An object of the'invention isthe provision of an apparatus for flushing drains'in which a rubber'hose has one endreceiv'ed by the usual faucet of a sink or other similarjinstrumentality with the other end speciallyconstructed to fitsnugly into the drain opening of the sink, the'last mentioned end of the tube 'being progressively expanded and provided with a hollow head that is received by the drain opening, a tapered metal tube fitted snugly into the expanded end of the rubber tube with the inner operr end of the metal tube having the free edge inturned to prevent injury to the associated portionrof-the rubber tube, the water issuing from the. outer end of the metal tube being divided into a plurality of fine streams by a perforated plate, provision being made for attaching a rubber ring toth'eouter end-of the metal tube when the apparatus is'used in washing hair, dishes, automobiles or other articles to prevent the metal of the second mentioned cupshaped member from coming'into contact with such articles.

A further object of'the'invention is the provision of an apparatus for flushing drains of various types in which'afrubber hose forms a sealed connection between the spigot and the outer end of a drain passage, one end of the hose being expanded progressively and terminating in a cup-shaped head which fits snugly into the drain passage, a metal cup-shaped member having a hollow depending tapered tube received frictionally by the complementally expanded end of the rubber hose with the metal cup-shaped member nested frictionally within the cupshaped head and having a portion extending beyond the head and received by the outer end of the drain passage, the cup-shaped member and the head cooperating to seal the expanded end of the hose to the drain passage so that when water is forced through a perforated plate in the cup-shaped member, the pressure of the water will cause flushing of the drain pipe.

This invention is best understood from a consideration of the following detailed description in connection with the accompanying drawings forming part of the specification, nevertheless, it must be borne in mind that the invention is not confined to the disclosure, but is susceptible of such changes and modifications as shall define no material departure from the salient features of the invention as expressed in the appended claim.

Figure '5 is a longitudinal I section of another form of fiushing apparatus having provision-for attaching 'thereto'the usual sprinkling nozzle, and

Figure 6 is a'longitudinalsection of a form of the flushing apparatus for use iii-cleaning sewers or manholes.

Referring more particularly" to Figures lto inclusive, 1 I udesignates =:a =rubberf tubing or hose whichhasasmall expandedend I I adapted'to be forced onto the end of a-mixing faucet l2 of a sink or basin I23. 'jThe faucet in this case may be swingably mountedandwill supply hot or cold waterdepending uponithe selection of a pair of The en'dl'l lof thetube may be applied when twoiare ei'ruilr iyed.

The other end M of the rubber tubing is expanded progressively and terminates in a cupshaped head l5 having the outer wall tapered as shown at Hi. This tapered head fits snugly into the upper open end of the usual drain pipe leading from the sink or basin to the sewer pipe. However, the sink or basin has a discharge opening in the bottom in which is sealed the upper flanged end of a metal pipe forming a receptacle i! for the usual rubber or metal stopper. The head [5 has a configuration substantially identical with that of the usual rubber stopper so that said head will fit snugly and frictionally in the receptacle.

A metal cup-shaped member 20 has a tapered metal tube 2| extending from the inner end thereof and formed integrally therewith. The tapering of the tube 2| is identical with the taper of the expanded portion I4 of the hose H3. The periphery of the inner reduced end 22 of the tube is swaged over to eliminate a sharp end which may cause injury to the hose. The outer end of the cup-shaped member 20 extends beyond the outer periphery of the head l5 so that a portion 23 of said member will project into the receptacle IT. A perforated plate 24 is seated and retained within the member 20 inwardly of the portion 23.

The member 20 is formed with a peripheral groove 25 in the exterior surface thereof, inwardly of the portion 23 and the head 15 is formed with an interior annular rib 26 which will seat in the groove 25 when the tube 2| and member 20 are forced into the expanded portion l4 and the head [5 of the hose so that the tube and member will be firmly held in place in the hose.

During operation of the drain fiusher just described, the smaller flared end ll of the hose is attached to a spigot or faucet 12. The head 15 is forced into the receptacle 1! of the sink and the water is turned on with sufiicient force to fiush the drain. If desired, the head l5 may be used as a stopper.

In Figure 4 there is illustrated an attachment which may be applied readily to the portion 23 of the metal cup-shaped member 20. This attachment is in the form of a thin walled rubber sleeve 21 which is forced over the outer wall of the portion 23. The sleeve 21 is employed when washing the hair, dishes and automobiles, and the attachment may also be used for massaging the scalp and body. The fre projecting end of the sleeve is flexible and prevents the metal parts of the device from coming into contact with articles being washed while providing a scrubbing action. The tapered tube 2| fits air and steam tight within the expanded end [5 of the hose I 0.

Figure 5 illustrates a form of the device which provides an integral formation of the metal cupshaped member 20 and a Well known form of nozzle 28 as employed in connection with a garden hose. The tapering tube 2| is fitted airtight in the tapering end M of the hose l and in use, the hose [0' would be of a length to serve the purposes intended, such as a fire hose or for ordinary sprinkling purposes.

In Figure 6 there is shown a more rigid form of apparatus for flushing larger drains, such as sewers and manholes. This form embodies a progressively expanding or tapered tube 2| as in the previous forms, but of larger proportions, the corresponding parts being identified by dual prime marks. The present form diifers over the form shown in Figure 5, in that the head is provided with headed pins 29 firmly fixed in the 4 top wall of the head and are adapted to be engaged by a suitable tool for withdrawing the head 15 from a manhole, since the head is tightly wedged into the manhole.

In all of the forms shown and described, it will be noted that the rubber hose and the tapered tube and associated head are secured together in a steam and water tight relation without the use of threaded connections, and it will also be noted that the tubes 2|, 2| and 2|" are of such lengths that they may be employed as a. handle in manipulating the device.

I claim:

A flushing and cleaning apparatus comprising a rubber hose having one end adapted to fit on the spout of a faucet, the other end of the hose being expanded progressively to form a tapered portion, a cup-shaped head connected to the larger end of the tapered portion, said head being formed of rubber and having an interior annular rib, a metal cup-shaped member fitted into the head and having a peripheral groove for receiving said rib, said metal cup-shaped member having a reduced portion projecting beyond the base of the head, a flexible cleaning element mounted upon the exterior surface of the projecting portion of the metal cup-shaped member, and said metal cup-shaped member having a tapered tube disposed within the tapered portion of the hose being of substantial length to provide a rigid handle portion.
